You raised a possibility that PCRE bugs affect also various Python
packages. Quite timely alert, I would say, and from all what we
know by now you were right. After that we got some followups on
the topic and some which left me somewhat baffled.

Indeed I wrote that. But this is about bugs in 'pcre' package
itself. Fixing that does not seem to help 'python<whatever>'
as that appears to re-cycle that code with security bugs directly
and not using 'pcre' as a library. Even if that would be used
as a statically linked library then all affected packages would
need to be at least recompiled (but most likely they need direct
patches).
So the report you qoute is not sufficient as bugzilla entries
are for a package and not for a bug with a list of all possible
packages where this may apply. Therefore we need a corresponding
entry in bugzilla. If you cannot and/or do not want to do that
then say so and somebody else will have to write something up.
